Group: Summary
  The map was published as part of a study of the fractured bedrock aquifers
  in the state of New Hampshire.  The digital data are intended for use by
  all government, academic, commercial, or other agencies in need of digital
  geologic map information.
  
  Not intended for use at scales larger than 1:24,000.
  
  Cartographic point coverage for ductile geologic structure data.
  
  The geologic data was mapped during the summer of 1998 at a scale of
  1:24,000.  The bedrock geology was mapped using standard techniques.
  Locational information was provided by Rockwell PLGR+96 GPS receivers
  using the federal precise positioning service.
  
  The line and polygon data were compiled on a mylar greenline of the
  7.5-minute quadrangle and scanned at 400 dpi on an Anatech Eagle 4080T
  scanner.  The raster files (TIF) were converted to vector files (DXF)
  using GTX OSR version 2.0 raster-to-vector conversion software.  The
  vector files were imported to Arc/Info version 7.0.4. Point data
  were collected with GPS and hand held 3COM Palm Pilot III PDA computers.
  Data from the PDAs were combined in Microsoft Access, and then imported
  as ASCII text files and (dbf) files into Arc/Info.  The Arc/Info coverages
  were registered and transformed to the New Hampshire State Plane Coordinate
  system.
  
  The geology dataset was printed and visually reviewed by the map authors
  and other USGS staff for geologic integrity, completeness, and accuracy
  of linework.  The report received a standard internal peer review as
  per USGS Open-File Reports.
